  • The development of laundry treating machines, in particular laundry dryers, has led to the use electric motors controlled by inverter circuits in order to obtain a better performance in term of reduction of energy consumption. Said inverter circuits allow that the rotational speed of the controlled electric motors may be changed and adapted to the laundry treatment requirements. In particular, the electric motor is provided to rotate a laundry drum at different rotation speed. Further, the electric motor may be provided to drive a compressor of a heat pump system installed inside the laundry treatment machine, wherein the rotational speed of the compressor is variable.
  • The inverter circuit for controlling the electric motor is arranged inside the laundry treatment machine and generates electromagnetic emissions. Said electromagnetic emissions may disturb other control circuit and wirings of the laundry treatment machine.
  • In order to limit the electromagnetic emissions the use of an anti-interference filter is known. The anti-interference filter has to be arranged very close to the source of the electromagnetic emissions, i.e. the inverter circuit, in order to work efficiently. However, it is not possible to provide the anti-interference filter as an integrated part of the inverter circuit, since the size of said anti-interference filter is too wide. Thus, the inverter circuit with the integrated anti-interference filter would cause space problems inside the laundry treating machine.
  • EP 1 666 660 A1 discloses a laundry drying machine with a laundry drum. The laundry drum is driven by an asynchronous motor able to drive said laundry in both rotation senses. The asynchronous motor includes a main coil and an auxiliary coil permanently interconnected via a capacitor and switchably interconnected via a further capacitor. Said capacitors are provided for regulating the torque supplied by the asynchronous motor. However, the capacitors have often a wide size. Thus, the capacitors cannot be integrated on a circuit board with a usual size. Otherwise, an appropriate circuit board would require a very large space inside the laundry treating machine.
  • When the anti-interference filter is installed separately from the inverter circuit or the capacitors are installed separately from the torque control circuit, an appropriate placement of the anti-interference filter or capacitors, respectively, may be problematic in the laundry treating machine. The most appropriate location of the anti-interference filter in order to ensure an efficient decrement of disturbance may not coincide with a sufficiently free place inside the laundry treating machine. In a similar way, an appropriate location of the capacitors may not coincide with a sufficiently free place inside the laundry treating machine. Further, the location chosen for the anti-interference filter or capacitors has to ensure safe operation and safe conditions in case of an incident, for example a fire of the anti-interference filter or capacitors, respectively. Moreover, a location of the capacitors is preferred, which allows short wires between the torque control circuit and the capacitors.
  • It is an object of the present invention to provide a laundry treating machine, which overcomes the problem of the position of the anti-interference filter or capacitors, respectively, inside said laundry treating machine.
  • The object of the present invention is achieved by the laundry treating machine according to claim 1.

    • the electrical component is arranged in a second position and inside the casing,
    • the second position is spaced apart from the first position, and
    • the second position is arranged close to the electric motor.
  • The main idea of the present invention is the supporting housing for receiving the electrical component of the control circuit on the one hand and the relative positions of the components to each other on the other hand. The supporting housing allows an appropriate position of the electrical component inside the laundry treating machine.
  • Preferably, the supporting housing comprises a wiring support. This contributes to a reduced complexity.
  • Further, the supporting housing may comprise at least one fire resistant material. Thus, the supporting housing creates a shield against fire.
  • Moreover, the supporting housing may comprise a box-like shape with on open side. The open side allows a fast assembling of the electrical component in supporting housing.
  • In particular, the open side of the supporting housing is directed at a side wall of the casing.
